AUTOMATIC FILM-SPOOI'ING- MACHINE.

Application led May 31,

To all whom t 'may concern.'

HAYWOOD G. DEWEY, citizens of thevUnite'd.

States of America, residing at Rochester, in the vcounty of Monroe and State of New York, have invented certain new and useful Improvements in Automatic Film-Spooling Machines, of which the following is a full, clear, and exact specification.

This invention relates to 'a process for assembling photographic roll film cartridges and to a machine in which such process may be automatically carried out.

Such cartridges include interwound strips of film and protective paper. with, sometimes, carbon paper used in the making of light printed legends in the camera. Such cartridges have been assembled on various machines, among them that described in application Serial No. 516,229, filed November 18th, 1921, by John G.' Jones, one of the present inventors. In all such machines, even the one above mentioned, several operations are necessarily performed by hand by an operator in'a very dim illumination, and it isv necessary to stop winding to perform these operations. Among the objects of this invention are to provide a process including a series of steps, which, While ca- 'of apparatus or by hand, lendthemselves particularly well to performance by an automatic machine, and to provide a machine -whch will be entirely automatic in operation,it being necessary to feed to it at the proper points supplies of em ty spools and long continuous strips of lm, prepared backing paper and prepared sticker band material. The machine will perform the various operations necessary in the correctly timed order and deliver a completed.

cartridge. Other objects will appear hereinafter.

Reference will now be made to the accom'- panying drawings 1n vwhich the same-reference characters referthroughout to the same part. It is to beunderstood that inthe drawings and particularly in those figures including diagrammatic showings, certainr disclosure is jiptendcd 'particularly to point pable of being carriedout on various types 1923.

out and -fully describe the features involving the invention as pointed out in the claims. It is to .be understood that the timed relation in the actuation of the several mechanisms is obtained by such proportionsand relations of mechanical-parts as Vmay be necessary for the particular materials used. For this reason such mechanisms are not shown in such detail as would merely render the drawings unnecessarily complex, but they are indicated with sufficient fullness for a skilled machine designer to design a machine and the synchronization and relation of parts is very fully stated.

Fig. 19 is a chart showing the timed relation of the movement vof the several parts.

Referring to the machine shown in Fig. 1, the base 1.supports 'the various moving parts upon suitable bearings, most of which are not shown, not being necessary'to an yunderstanding of the mechanism. The roll 2 of film QF of suitable width, is carried by shaft 3. The film band is carried about roller 4, suction wheel 5, between the paster-v applying rollers 6 and 7, across suction belt 8, between paster-applying rollers 9 and 10, across suction belt 11, into a position from which it is woundfupon a spool S.

To tension and guide the film band F properly, roller 4 is carried by lever 12 pulled by a spring 13 against the film and pivoted at 14 to base 1. A second arm 15, independently pivoted at 14, engages a brake rod 1.6 having at 17 a pin and a slot connection therewith and pressed by spring 18 to the braking position. If'tlie film should run too freely from reel 2, roller 4 would swing to the left (Fig.- 1) and lift finger 12 from contact with arm 15, thereby permitting spring 18 to raise arm l5 and apply brake 18 to the reel.y If the'freverse is true, roller 4 will be drawn against spring 13 to a position inl which arm 15 will release brake 18. This mecha# nism governs the film feed.

The film is moved over suction drums and suction belts which retain the film in the 'proper path without damage to the sensitive photographic emulsion on one side or to the backing material on the other side. In Fig. 2, a typical roller is shown as consisting of a shell 19 perforated vat 20 and revolving around a fixed block l21 which has a portion 22 cut away to form 'avacuum chamber. A pipe 23 may `exhaust the air from this chamber. The shell moves the film. It isobvious that so long as the film lying upon the perforated shell 19 is above the vacuum chamber-22 it will be retained against the shell but when the apertures move so as to lie over the block 21 the film may pass from the shell. 'In the drawing, dashed lines in Fig. 1 indicate those portions of the rolls which will not hold the film upon the shell. The vacuum belts 8, 11 and 40 are constructed, on the saine principle as the rolls, with foraminou's belts 24 which. when passing over the vacuum chambers 25, holdthe film,

but when the film passes beyond'these chambers, it is no longer held. These means provide a method for supporting and movingthe film securely but with a minimum of friction, and without causing abrasion.

The film strip F ypasses about suction -gear train 34, 35, 36, 37 and 38.

shaft 27 through av cam disk 28, pivotedlever 29, a rack 30 pivoted thereto, pinion 31, pawl and ratchet 32 and 33, ,and the Thuscam disk 28 causes wheel 5 to turn the distance necessary to measure a film length, after which the knife 26 is actuated to cut the film. The cam disk 28 has a cam groove 28 in which a pin 27 on lever29 engages.-

This length is then drawn forward to the position shown at L, in which position the rear end of the severed strip is spaced from the knife and the unsevered end of the film not shown in detail but comprising as a whole a mechanism 39, moving the belt 8.

The secondl vacuum belt 11 is moved synchronously with belt 8' by a. similar set of mechanism 41, indicated diagrammatically, from-drive shaft 27 through lever 29 and rack 30", and the movement of belts 8 and 11 are timed to act together in a relation that will be more exactly' described later. Belt 11 positions the strip of film in the space indicated by M.v a y From this belt the film moves into a convolution of the paper P being wound on the spool S.

The front and back pastels, 42 and 43, (Fig. 8) are simultaneously applied in the following manner: As the film F passes between rollers 6 and 7, one portion 44 of more so when heated. This paster-dispens' ing and conditioning means is fully described in our copending application Serial No. 640,261, filed May 19, 1923. l

Rollers 9 and 10 are at the same time applying paster l42 tothe other end of the film band. This paster is preferably of the type shown in our Patent No. 1,500,393, granted July 8,1924, and in our application Serial No. 714,747, filed May 20, 1924, and consists of a strip of material'50 having a waterless adhesive portion 5l anda water soluble adhesive portion 52 and bemg free from adhesive between these portions. As

' shown in Fig. 10, this paster is fed transversely to the film and cut on the line 54, after which the suction portion 55 of wheel applies it (after being heated the waterless paster) to the film band F, the feeding and chopping arrangement being analogous to that for paster 43. -The dispensythe typ Fig.. 9 shows ing means for this sticker band is also of e'fully described in our application Serial No. 640,261. yIt is to be understood that these pasters are prepared at such intervals of tune that one will be ready when the vacuum section of the respective rotating feed roller makes a revolution and passes theprotruding end. The details of these mechanisms are suiciently described in the application referred to. In Figs. 10 and 11 the path of travel of the film is indicated in dot-dash lines and these figures show the relation to that path of the stickers.

Moving on to the left (Fig. 9) thefilm, with pasters attached, is caught in a convolution of paper P and is Wound upon the.

spool S, being directed thereto by guide 1000 The paper P is carried in a roll at 56 from v clined Walls 151, forming narrow portions at which are transverse weakened severing lines 150. These form the tapered end portions of the paper strips for the individual spools of film. At intervals along the strip P, and properly positioned With respect. to the lines 150 are pasters 153. which are eventually Wound into the convoutions of the paper near the core of the spool. When rewound in a camera upon another spool the paper can lbe secured by these pasters which then will be positioned at the outer convolution. It is to be understood that the paper as shown in Fig. 7 is fed toward the right. the relation of this sticker in being fed.

rEhe threader 61 may consist of the structure shown in Fig. 6, Where the blocks 63 and 64 slide freely upon rods 65 .and

Rod 66 is movable, swinging. upon arms 67 and 68, the latter having an ernia 69 contracting with the cam 70 carried by rotating shaft 71 so that the rod 66 will be periodically swung from the position shown in this figure along the line of the arrows.,

black has upwardly extending blades only enough firmness to position t 72 and 7 3 Which may enter the slot 74 of a spool S and carry the end of the paper therethrough. The blocks are given an up-anddown movement upon rods and 66 by a rod 75 terminating in a head 76 contacting with 'a portion .of the bottoms of blocks'63 and 64vand actuated by roller 77 which moves'in cam slot 78 in a rotating disk 79. The movement given blades 72 and 73 by cams and 7 8'is such that at thelower extremity of movement they come together and graspthe paper, then carry the paper upwardly through lthe spool slot 74, theny they separate suiiiciently to release the paper, Withdraw from the slot and gradually open luto the position shown diagrammatically in Fig. 1. This movement is also indicated dlagrammatically in Fig. 6A. It Will be noted that in the form shown block 63 merely reciprocates in a straight line and the side- Ways movement is accomplished entirely through block 64. The first side movement of block 64 need only be a few thousandths of an inch in practice to release the paper, but after the blades are Withdrawn from the slot it is preferable to open the blades a considerable distance as shown.

The spool must be presented with the Wide edge 80 of the slot 74 toward the paper feed. rIfhis is done as follows: A rotary head conslsts of frames 81 and 82 (Fig. 3) facing each other'and periodically moved by'the Geneva gear 83 and pin 84, the latter being moved through shafts 85y and gears 86 from the power shaft 27.

The paper, When first inserted into the spool slot, lies' along the dotted line 210 (Flg. 1). A roller 211 is carried on an arm 212 pivoted at 213 to the main frame. Vhen the paper is threaded this'arm and roll lie 1n an inoperative position indicated in dotted line, but as soon as Winding of the paper on the spool begins, this arm and roller swing to the full line position shown. The paper assumes the full line position and with the cartridge readily engages the end of the film as itis fed forwardly by belt 11, past guide 1000. j

Vpools S are fed down chute 87 to the dispensing springfingers 215 and 216. These are so shaped and positioned that they Will hold one spool at a time in such a position that it will be engaged by thev mechanism now to be described. They hold them with hem. Such feeding or dispensing arrangements are well known.

The spool so held is engagedfat one end by the spring-pressed centering pin 88 which is cylindrical and' has a rounded head that slips into the round aperture 88 in the spool, and at the other end, which has a slot 94, by

vthe spring-pressed winding web 80. This web is automatically Withdrawn when the ange 90 of the web member contacts Wlth u sary revolutions 'when the rotating head is.

cam`91, drawing back the web against the spring 92. lVhen flange 90 is released by notch 93 in cam 91, the web 89 may be `out of alignment with spool end slot 94, butjthis is not material because when shaft .95, with which the web has a pin and slot connection 95', is rotated (as will be hereinafter described) the web will either rotate until it drops into the slot, should' the spool S` remain stationary, or should vthe spool be rotated by frictional contact the spool will turn until spring 96 forces fingers 97 into the wide edge 80 of slot 74. This locates the spool slot and stops the spool the desired position, and web 89, if uncngaged, continues to rotate until it engages the slot 94.

To rotate shaft 95 the following mechanism is used. 0n shaft 95 is a clutch member 98. A friction block 99 is carried by the slide block 100 movable along shaft 101A by the lever 102. Lever 102 is actuated by cam 103 timed to rotate shaft 95 the few necesstationary in the position shown in Fig. 3. The block 99 is then 'moved from contact. with clutch 98, whiciL is, of course, carried around with the rotary frames 8 1, 82. -lVhen at the winding position, clutch member 98 is contacted by another clutch member 104, .driven by shaft 105 and bevel gears 106, and actuated by lever 107 controlled by cam 108, to drive the spoolv to wind the film and. paper thereon. This is timed to operate immediately after the withdrawal of blades 72, '73 from slot 74. Shaft 109 actuates shaft 101 throkugh gears 110, and shaft 111 through a gearf112 and worm 113, shaft 111 carrying the cam wheel 114 with theabove mentioned cams 103 and 108.

The spool-locating lingers 97 carried by spring 96 are actuated in the following manner: Sprmg 96 is carried on shaft 115 (Fig. 5) which 1s mounted in suitable bearings 116. A lever' 117 is pinned to this shaft, and

when the lever is moved to rotate the spool, n

roller` 121 raises lever 117 moving shaft 115 to brlng spring 96 into the position shown in full: lines, Fig.4 5, and, when the spool is turned untilthe wide edge 80 of the slot registers with the. fingers .97, these will be 'pressed into the slot-dotl and dash lines Fig. .ri-and p'roperly locate the spool. The finger-Savill be" retained inl this position until the sioeldrivingf shaft is no longerrgtated by the mln driving shaft T01 so that there is `-no. chance of changing the location of' the slot after .the proper position is once determined-fi-fter the fingers 97 engage the slot 74, the spool will be fixed in position and the friction clutch members 98 and 99 will slip. This will be for only a very few revolutions of member 99.

The rear end of the paper is given a fold 299 Fig. 1) and shown in detail in Figs. 14 to 18 inclusive. This folder also severs the paper along theweakened line 150. When the paper band P is stationary, the folding arm 300, and the guide arm 301 having'an outwardly flared end 303, are moved to the position shown in Fig. 14 in which the paperv .b-y the automatic mechanism indicated at Shaft` 304 does not turn in bearing 330 but carries a key 304 which engages slot 320. so that-.the shaft slides without turning.

A spring 311 normally holds roller 307 car-- ried by yoke 306 against cam 308, which is keyed at 310 to a sha-ft 309 driven in synchronism with the other parts of the machine. Cam 308 moves shaft 304 to the position shown in Fig. 14 when the paper bandl is motionless, at which time gear 313. causes gear 312 to revolve half a turn, severing'the 17 and 18.

Vhen folded as shown in Fig. 18, the cam 308 permits the arms 300 and 301 to be withdrawn or retracted into the position shown in dashed lines-F ig. 14, in which position the parts will remain stationary while they convolutions of film and on the spool. y

.As is shown inrFig. 12, the fold 350 ]ust paper are wound 'described is on the outer end of the backing paper and greatly facilitates opening the spooled film for use in loading a camera, as it. furnishes a shoulder against which seal 351 may be broken. l

After winding the convolutions of. paper and-film on'spcol S, the rotating frames 81, 82 carry the spool to a position in which a spring clasp 130 grasps the spool S. The Winding web 89 is first withdrawn from the endof the spool by a suitable cam, lnot paper strip P along the weakened line 150, "and folding itat 350 as shown in Figs. 16,

shown, but similar to 91, above described.

A of clasps are carried by turret l131, which is moved step by step by Geneva gear 132, 'pin 133A and suitable gears 134, 135,v shaft 1 36, gears 137, shaft 138 which is connected to, or is preferably an extenvsion of a shaft 85 driven by 'the' power shaft 27. Turret 131 moves in timed relation with the carriers 81,. 82 and after nism indicated at '145, but not shown in detail, it dropsthe spools into a chute 140,-

erence characters 13() to 145 form the subject matter ofA our other copending application,

Serial No. 640,262, filed May 19, 1923, the details will not be more fully described herein. A

Since the length of the paper and film wound on the spool is accurately predetermined, the outer end of the paper will lie at a known relation and the cartridge isso grasped and held by clasps 130 that the sealing paster will be applied over this end.

We alsocontemplate introducing sheets of carbon paper in assembling cartridges adapted to have inscriptions written on the film' in the` camera in a well known manner. In Fig. 13 is indicated diagrammatically the assembly permitting such an operation, thel iilm F and substantially the same path as inlIfig.' 1. A roll of carbon paper .Pc is introduced. In addition `te paster-applying station 10 in the path of the film, a similar pasterapplying station 204 .is situated in the path of the paper; and a feed roll 202 similar to feed roll 9 is used; Additional feed rolls 207 and 201 cooperate wit'h 9 and, 202 respectively and with these cooperate chopping knives 208 and 203 respectively.I This arrangement permits the introduction of carbon paper by either of two paths as indicated by dotted lines. In one case the carbon paper is fed in lengths, determined by the timed operation of rollers 201, 202 and knife 203, to the paper P to which it is attached by a sticker applied at 204. In the other case it is fed in lengths determined by the timed operation of roller `207 and knife '208, to-.the film F to which it is attached by the vsticker already described asf attached at 10. In either case it is assembled in the cartridge in the winding as heretofore described. v

The 'mechanism connecting the central power shaft and'each of the above described intermittently operating partsv are not shown with any fullne astheir details are of no importance and a complete exact drawing would conceal rather than disclose r the invention. yIt-is to be understood, Ihowever, that mechanisms 'analogous to those indicated for the actuation of drum 5, belt 8 and the like, serve to operate the several parts at the proper time, and'that the laying out of the details of the-cams and the proportioning of the parts, While important, can be done by a skilled designer. .Their cooperation may be much more readily understood. from a chart showing their timed relation than from a drawing shaw-A paper P passing through` ing the mechanism itself; and this method of description will, therefore, be employed.

It is to be understood that. three strips of film are" simultaneously being fed through the apparatus. A While the first is being fed from belt 11 to the cartridge, the second is being fed from belt 8 to. belt y11, and the third fromidrum 5 under the knife to' belt 8 to be severed. At each cycle the frame 82 is advanced a quarter turn, the spool that is vgrasped and centered at the upper or first position,- beingidle during the second cycle` and woundl with film and paper during the\ third cycle. At the fourth cycle the wound cartridge is moved tothe left and grasped by a clamp 130 on the spider 131. This spider m-oves a sixth revolution at each cycle, and applies the sealing strip l351 inthe manner described in ourabove .the dashed cross lines indicate twelve Iintervals of time. The light and heavy portions of the vertical lines indicate that the part referred to at its top is respectively motionless or in operation during the corresponding time" intervals. This figure shows the time relation of the parts operative to wind the film and paper. I-Ience to follow a single strip of film through, it will be necessary for three cycles to elapse. VVhileth'e intervals of time are here indicated as equal in len th it is to be understood that this is by no means usual, and is so shown merely for convenience, and that the relative vlength of the various intervals must necessarily be adjusted to suit the requirements of the work. .We have lying on belt 8 in the position indicated by L and the third on the belt 11 in the positionindicated by M. The film'F remains still until the cycle is about a. quarter through, then drum 5 turns, moving the film under chopper 26 to belt 8, lwhich meanwhile, is moving. Vhen a length of film of the predetermined length has passed under knife 26, which is indicated as occupying four intervals of time IV to VII), both belt 8 and drum 5 stop and the knife 26 is at once operated (Interval VIII) to sever thelength of film. Belt. 8 then (Interval IX) moves the film to the position` indicated at L and the two band applying rolls 71a-nd 10-operate simultaneously (Interval X) applying sticker bands yto both ends of the film strip. The film remains thus until the band 8 begins to move in the next cycle at the same time that drum begins to advance the succeeding stri of film. Belt 8 moves the film with stic ers attached to belt 11 whichl is also vmoving at thistime and the film is drawn over upon this belt which continues to move (Interval VIII) for a very short distanceiafter belt 8 has stopped and draws the rear end of the film past the sticker-applying station at 7 to a position indicated at M. The front of the film on belt 11 is now under guide wound on theA spool.

1000 and slightly spaced from the spoolwrapping station. This separation of the films prevents interference between a sticker 43 already applied to thev rear end of the film on belt 11 and a sticker 42 being applied to the lead end of the film on belt 8.

Thefilms remain in the described positions until this second cycle is completed.

l Just before the completion of the cycle (Interval XI), arm 212 swings down to the dotted line position to give the threader 61 room to operate and at the same time (Intervals XI and XII) the frame 82 moves a new spool S into loading' osition. As

soonas this cycle is complete threader 61 grasps the lead end of the paper P and inserts it in the slot of the spool, the belt 40 moving slightlyat the same time. As soon as the jaws are retracted, clutch 104 is rendered operative to turn the spool and wind the paper thereon, belt 40 also moving the paper, (Intervals II and III) and arm 212'swinging back tofull line position. VEnough paper is wound on' the spool to constitute the required lead strip for the film and then belt 40 and thesp'ool stop momentarily. During the latter part of Interval II, belt 11 has begunto move and the lead end` of the film with paster 42 is forced into the outer convolution of paper being The belt 40 and clutch 104 again operate and the paper and film are wound together on the cartridge, belt 11 feeding the rear end of the film forward` ly.. Afterthe stripof film is wound, the belt 11 continues to move only until the lead end of' the next strip is properly positioned at- M; but clutch 104 and belt 40 continue to move the paper until the rear lead strip is nearly wound. They then stop ,(Interval IX) and the folder 299 is operby the tight windiyng into adhesive contact with the protective paper, 'out the sticker 42 having only a dry adhesive in exposed position does not adhere to the paper.

In Fig. 1, the path of the film is shown as an unbroken line but it is to be understood that the film itself is in a number of stripswith spaces between as fully described. Fig. 9 shows the relation of the paper and two strips of film in the middle of the winding operation.

In previous methods of assembling roll film cartridges, it has been customary to wind a lead stri portion of rotective material on a spoo then stop t e spool while a sticker is attached to one end of a film strip, then wind the filmy and paper, then stop the machine while the rear sticker is attached, andthen complete the winding. By the process herein describedy the film. is prepared as a unit before being brought to the winding station, and it is necessary to stop the winding of the protective paper, if at all, only long enough to insure of the lead end of the ,film with its sticker being properly positioned. This process is, of course, applicable to windin -by hand or on other machines, and is of a vantage in that the winding process is more expeditiously carried out and can be done with a machine having a higher rotativel speed.

It is to be understood that the disclosure .herein is illustrative and that we contemplate as within the spirit -of our invention'al. such embodiments, improvements and equivalents as fall within the scope of the appended claims.
